' IMPROVEMENT IN straarvfctrrrnlts.-

TO ALL WHOM IT `MAY CONCERN:

Be it known that I, Jost-:Pn W. BROCKWAY, of the city, county, and Stateof New York, have invented and made a certain new and useful Improvementin Cutters for Straw, Hay, &c.; and I do hereby declare 4the fol' lowingto be a full,'clear, and exact description of the said invention,reference being had to the annexed drawing, making part' of thisspecification, whercinl Figure 1 is an elevation at the end ofthemachine.

Figure 2 is a section transversely of the feeding-rollers.

Similar marks vof reference denote the same parts.

I make use of a. revolving` stock, carrying a cutter or cutters placeddiagonally to the radial line, and apply the same to a feeding-trough insuch a manner that the knife or cutter acts with a drawing cut upon thestraw or similar material, to separate the samc into short sections.

The knife in its movement operates diagonally to the stationary metallicedges at the end of the trough, so as to cut like shears. l

In the drawinga is a frame, supportingr the trough, b, that is ofsuitable size and shape, andc c are feeding-rollers, geared together atd d, as seen in tig. 1.

These rollers' c c are formed with longitudinal ribs on their surfaces,so as to act upon thestraw or other material, and feed the same withregularity through the trough to the cutters. l

The main shaft, e, of the machine is driven by power applied to thepulleyf, or by the hand-crank, g, and lt is a gear-wheel that acts uponthe upper gear, d, of the feed-roller 0;, and-I find it preferable toconnect the gears d d by the intermediate gears d d', to prevent said-gears d being so large.

c is a compound pinion, formed with straight teeth, taking the wheel la,and bevel-teeth taking the bevelwheel Z on the back of the cutter-stockm, thatis mounted at the end of the shaft z', set in bearings upon theframe ofthe machine.

The cutter-stock m carries the cut'tersfn, that are placed diagonally,as shown in iig. 1, so as to act with a drawing and shearing cut uponthe straw, and o o are metallic bars,lformng the end of the trough b,and against which the knives act like shears in completing thecutting-operation. i

The guard p surrounds the knives 1t, to prevent injury to the attendant.I prefer that this guard be stationary, and rather more than a halfcircle, as shown, but the same might be made as a circle, and attachedby arms to the stock m.

I prefer that the cutters n be formed as the arc of a circle, assho\vn,.but the cutting-edge might be straight, the diagonal positionbeing maintained so as'to act with a. shearing cut.

The stock mis to conform generally to the :hapeof'the cutters n, with awing or wings extending out from the central portion, and upon the outerportions, handles 1'; rare aiiixed, so that the cutters eanvbereciprocated by a direct application of hand-power tg the same, insteadof the cutters being revolved.

It' desired, the gearing can be disconnected, so that the cutters alonewill bemoved when reciprucated by hand.

What I claim, and desire tose'cure.by Letters Patent, i'sy 1. The cuttern and stock m, in combination with the handle r, applied directly tosuch cutter or stock, so thatthc same can be vibrated by hand, and swingin contact with the bars o o at the end of the feeding-trough,substantially as set forth.

2. The arrangement of gearing t, d, d', c, and l, in combination withthe feed-rollers c c, cutter-stock nt,

and cutters it, as'andor the' purposes set forth.

In witness whereof, I have hereunto set my' signature, thistwenty-fourth day of April, 1868.l

JOSEPH W. BROCKIVAY.
